Siliconera is reporting that a Simpsons game is in development by EA:

Spotted on various retailers lists is a new Simpsons game aptly called “The Simpsons Game”. Electronic Arts is listed as the publisher and the tentatively titled game is going to make appearances on the Nintendo DS, Playstation 3, Playstation 2, Xbox 360, PSP and Wii.

I would love a Simpsons game on the Wii, especially with cool Wii controls :)
